actionClass property
The SIDE-EFFECT family the target is resolved for — input
(set_text / type), tap (click / tap / navigate / select trigger),
toggle (check), slider (set_slider) — or null for read-only verbs
(read_field, highlight, scroll_to, find_candidates), which keep the
lenient ladder. A non-null class makes the text rung strict: whole-word
matches only ("PIN" never matches "Pincode"), an ambiguous winner is
REFUSED (ambiguous_target) instead of guessed, and an input whose
only match is a qualified label ("Name" → "Nominee Name") is refused as
target_mismatch.
